In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

At present, the mainstream millimeter-wave antenna design in wireless mobile terminals is an antenna array composed of more than two antenna elements to increase antenna gain and overcome the propagation loss due to the larger millimeter-wave band (compared to non-millimeter-wave band). However, the beam of the antenna array is relatively narrow, and it is often necessary to scan the beam to cover a wider space and maintain better wireless signal coverage, thereby satisfying the user's wireless experience. In addition, when holding a wireless mobile terminal, the hand usually easily blocks the antenna in the device, such as the millimeter wave antenna, which significantly reduces the performance of the antenna and degrades the user's wireless experience. Moreover, millimeter wave (compared with non-millimeter wave) has more frequent and severe scattering behavior in wireless transmission, so the degree of polarization matching of wireless electromagnetic waves also plays a key role in the quality of millimeter wave wireless communication.

The proportion of display screens in most wireless communication electronic devices is getting higher and higher than the size of the display screens, so the placement of antennas in the devices is often limited, and it is considered to integrate the antennas in the display screens. Specifically, when a millimeter-wave antenna array is integrated in a display device, the millimeter-wave antenna array Each millimeter wave antenna unit is respectively connected to a millimeter wave RFIC (Radio Frequency Integrated Circuit, radio frequency integrated circuit). As shown in FIG. 1 , a plurality of millimeter-wave antenna units 102 are arranged at intervals in an electronic device 104 , and are electrically connected to a millimeter-wave radio frequency integrated circuit 108 through a millimeter-wave radio frequency signal line 106 .

However, the polarization directions of the millimeter-wave antenna units 102 are the same, so it is more likely to have a polarization mismatch for receiving wireless electromagnetic waves, thereby causing a large wireless communication blind area, resulting in poor wireless experience for users. Moreover, MIMO (multiple-input and multiple-output, multiple-input and multiple-output) cannot be realized, resulting in that the wireless data transmission rate cannot be further improved, thereby affecting user experience again. To sum up, the wireless communication quality of the electronic device 104 does need to be improved; however, if multiple RFICs are used to improve the communication quality, it will cause a negative impact on product competitiveness such as increased system cost and increased product size.

Based on the above reasons, the present invention provides a display screen with an integrated antenna, a display device and electronic equipment. The display screen includes a plurality of antenna units, and the plurality of antenna units include a first antenna unit and a second antenna unit with different polarization directions. , at least one first antenna unit constitutes a first antenna, at least one second antenna unit constitutes a second antenna, and the first antenna and the second antenna are alternately arranged. The first antenna unit and the second antenna unit with different polarization directions are arranged alternately, so that the first antenna and the second antenna can increase the beam coverage of the antenna due to different position settings, thereby reducing communication blind spots, To improve communication quality and user wireless experience. In this way, the possibility of being blocked (such as being held by hand) and simultaneously degrading the performance of all antennas with the same polarization direction can be reduced, thereby enhancing the user's wireless experience. Moreover, this design can also form complementary polarizations to reduce the probability of wireless electromagnetic wave polarization mismatch, and also reduce communication blind spots to improve communication quality and user experience. Furthermore, based on this design, the mutual coupling between the first antenna and the second antenna can be reduced, thereby improving antenna performance and user wireless experience.

The display screen provided in the embodiment of the present application may be an OLED (Organic Light-Emitting Diode, organic light-emitting diode) display screen, an LCD (Liquid Crystal Display, liquid crystal display) Display screens, etc., are used in electronic devices such as mobile terminals, tablet computers, notebook computers, wearable devices, and vehicle-mounted devices.

The display screen includes a first antenna unit and a second antenna unit with different polarization directions, at least one first antenna unit constitutes the first antenna, at least one second antenna unit constitutes the second antenna, and the first The antennas and the second antennas are alternately arranged. In this way, the first antenna and the second antenna can increase the beam coverage of the antenna due to different location settings, thereby reducing communication blind spots, so as to improve communication quality and user wireless experience. This can also reduce the possibility of being blocked (such as: hand-held) and degrade the performance of all antennas at the same time, so it can enhance the user's wireless experience. Moreover, this design can also form complementary polarizations to reduce the probability of wireless electromagnetic wave polarization mismatch, and also reduce communication blind spots to improve communication quality and user experience. Furthermore, based on this design, the mutual coupling between the first antenna and the second antenna can be reduced, thereby improving antenna performance and user wireless experience.

In some embodiments of the present application, as shown in FIG. 2 , the polarization direction of the first antenna unit 11 and the polarization direction of the second antenna unit 12 are orthogonal. In this way, on the premise that the polarization direction of the first antenna unit 11 is different from that of the second antenna unit 12, mutual coupling between the first antenna unit 11 and the second antenna unit 12 is avoided to the greatest extent, It can effectively improve the communication quality.

Wherein, the polarization direction of the first antenna unit 11 is the trajectory direction of the electric field tip of the electromagnetic wave radiated by the first antenna unit 11 with time, and the polarization direction of the second antenna unit 12 is the radiation direction of the second antenna unit 12. The trajectory direction of the tip of the electric field of the outgoing electromagnetic wave changes with time.

For example, the polarization direction of the first antenna unit 11 is longitudinal polarization, and the polarization direction of the second antenna unit 12 is transverse polarization; or, the polarization direction of the first antenna unit 11 is transverse polarization, and the polarization direction of the second antenna unit 12 is transverse polarization. The polarization directions of the two antenna elements 12 are longitudinal polarization.

In other embodiments, the polarization direction of the first antenna unit 11 and the polarization direction of the second antenna unit 12 can also be other angles, that is, the polarization direction of the first antenna unit 11 and the polarization direction of the second antenna unit The polarization directions of 12 are not orthogonal.

In some embodiments of the present application, as shown in FIG. 2 , the display screen 10 includes an edge area, and at least one of the first antenna 13 and the second antenna 14 is disposed on the edge area of the display screen 10 . In this way, the respective signal lines connected to the first antenna 13 and the second antenna 14 are also arranged in an area adjacent to the edge of the display screen 10 , which can avoid affecting the display effect of the display screen 10 .

Wherein, the edge area of the display screen 10 refers to the area adjacent to the side elevation of the display screen 10 . Specifically, the distance between the antennas disposed at the edge of the display screen 10 and the side elevation of the display screen 10 is smaller than the distance from the center of the display screen 10 . In practical applications, the display screen 10 includes a display area and a non-display area at least partially surrounding the display area. The edge area of the display screen 10 may include the non-display area, and may also include a part of the display area adjacent to the non-display area.

Exemplarily, as shown in FIG. 2 , the first antennas 13 and the second antennas 14 are alternately arranged in the edge area of the display screen 10 .

In some embodiments of the present application, the first antenna 13 and the second antenna 14 can be arranged in any area of the display screen 10 , and can be alternately arranged in any area. That is, at least one of the first antenna and the second antenna can be arranged in the display area of the display screen 10; at least one of the first antenna and the second antenna can be arranged in the non-display area of the display screen 10; The first antenna is disposed in the display area of the display screen 10 , and the second antenna is disposed in the non-display area of the display screen 10 . exist

In some embodiments of the present application, the frequency band of the first antenna 13 is the same as that of the second antenna 14, which is beneficial to improve the gain of the antenna array, the degree of polarization matching, and the coverage of the beam in space degree, the strength of signal reception, and the degree to which antenna performance can be reduced due to hand-holding or other obstructions.

Among them, the frequency band is the frequency range of electromagnetic waves, which can be divided into: very low frequency with a frequency range of 3kHz~30kHz, corresponding to very long waves with a wavelength range of 100km~10km; low frequency with a frequency range of 30kHz~300kHz, corresponding to a wavelength range of 10km~1km long wave; the frequency range is 300kHz~3000kHz medium frequency, the corresponding wavelength range is 1000m~100m medium wave; the frequency range is 3MHz~30MHz high frequency, the corresponding wavelength range is 100m~10m short wave; the frequency range is 30MHz~ VHF of 300MHz corresponds to meter waves with a wavelength range of 10m~1m; UHF with a frequency range of 300MHz~3000MHz corresponds to decimeter waves with a wavelength range of 100cm~10cm; UHF with a frequency range of 3GHz~30GHz , corresponding to centimeter wave with a wavelength range of 10cm~1cm; extremely high frequency with a frequency range of 30GHz~300GHz, corresponding to millimeter wave with a wavelength range of 10mm~1mm; high frequency with a frequency range of 300GHz~3000GHz, corresponding to a wavelength range of 1mm ~0.1mm of simi wave.

In an implementation manner of the present application, the first antenna unit 11 and the second antenna unit 12 are configured as millimeter wave antennas. Exemplarily, the frequency band of the first antenna unit 11 is the 5G millimeter wave band, and the frequency band of the second antenna unit 12 is the 5G millimeter wave band. Among them, the current frequency range of the 5G millimeter wave band is 24.25GHz~52.60GHz.

Exemplarily, the frequency band of the first antenna unit 11 is the 5G non-millimeter wave band, and the frequency band of the second antenna unit 12 is the 5G non-millimeter wave band. Among them, the current frequency range of 5G non-millimeter wave band is 450MHz~7.125GHz.

In other embodiments, the frequency band of the first antenna 13 is different from that of the second antenna 14 . Specifically, one of the first antenna unit 11 and the second antenna unit 12 is configured as a millimeter wave antenna, and the other is configured as a non-millimeter wave antenna.

Different frequency bands are introduced below: When the first antenna unit 11 and the second antenna unit 12 are configured as millimeter wave antennas, as shown in FIG. 2 , multiple first antenna units 11 constitute the first antenna 13 , the plurality of second antenna units 12 constitute the second antenna 14 . In view of the high transmission loss of millimeter waves and the high sensitivity to occlusion, multiple millimeter wave antenna units are used to form a millimeter wave antenna array, which can improve the coverage of the antenna array's beams in space, the receiving strength of signals, and reduce the risk of hand-holding. Or other shades that degrade the performance of the antenna, so the quality of wireless communication can be improved.

When the first antenna unit 11 and the second antenna unit 12 are configured as non-millimeter wave antennas, as shown in FIG. A second antenna 14 is formed.

In some embodiments of the present application, as shown in FIG. 2, a plurality of first antenna units 11 and a plurality of second antenna units 12 are arranged alternately, which can avoid mutual coupling between two adjacent antenna units, so as to improve The communication quality of the first antenna unit 11 and the second antenna unit 12 .

In an implementation manner of the present application, as shown in FIG. 2 , the first antenna units 11 and the second antenna units 12 are arranged alternately.

Specifically, as shown in FIG. 2 , the edge area of the display screen 10 includes a first edge area A, a second edge area B and a third edge area C connected in sequence, and the first edge area A and the third edge area C face each other.

For example, as shown in FIG. 2 , the first antenna units 11 and the second antenna units 12 are alternately arranged in the second edge region B of the display screen 10 . As shown in FIG. 4 , the first antenna units 11 and the second antenna units 12 are alternately arranged in the third edge region C of the display screen 10 .

In the second type, the first antenna units 11 and the second antenna units 12 are arranged alternately at two edge regions of the display screen 10 . For example, as shown in FIG. 5 , the first antenna units 11 and the second antenna units 12 are alternately arranged in the second edge area B of the display screen 10 and alternately arranged in the third edge area C of the display screen 10 . In this way, the spatial coverage of the beams of the antenna array and the receiving strength of the signal can be improved, and the degradation of the antenna performance due to hand-holding or other obstructions can be reduced, thereby improving the quality of wireless communication.

The third type is that the first antenna units 11 and the second antenna units 12 are alternately arranged in three edge regions of the display screen 10 . For example, as shown in FIG. 6 , the first antenna units 11 and the second antenna units 12 are arranged alternately in the first edge area A of the display screen 10 along the second direction, and in the second edge area A of the display screen 10 B are arranged alternately, and also arranged alternately in the third edge area C of the display screen 10 . In this way, the three edge areas of the display screen 10 are all equipped with antenna units, and the layout range of the antenna units is relatively wide, so it can effectively reduce the performance degradation of the shaded antenna and expand the spatial range covered by the beam, so it can improve wireless communication. Quality and wireless experience for users.

A plurality of second antenna units 12 are arranged on the display The third edge region C of the display screen 10 forms another group of second antenna unit groups 16 . A plurality of first antenna units 11 are disposed on the second edge region B of the display screen 10 to form a first antenna unit group 15 .

A plurality of first antenna units 11 are disposed on the second edge region B of the display screen 10 to form another first antenna unit group 15 . A plurality of second antenna units 12 are disposed on the second edge region B of the display screen 10 to form a second antenna unit group 16 . A plurality of second antenna units 12 are disposed on the third edge region C of the display screen 10 to form another second antenna unit group 16 . The second antenna unit group 16 arranged on the second edge area B of the display screen 10 is close to the first edge area A of the display screen 10, between two groups of first antenna unit groups 15; The first antenna element group 15 of the second edge area B is close to the third edge area C of the display screen 10, and is located between the two second antenna element groups 16, that is, the first antenna element group 15 and the second antenna element Groups 16 are arranged alternately.

The above two antenna designs can also reduce the mutual coupling between the antennas, and can effectively reduce the performance degradation of the shaded antennas and expand the spatial range covered by the beam, thus improving the quality of wireless communication and the wireless experience of users.

In some embodiments of the present application, as shown in FIGS. 2-8 , the first antenna unit 11 and the second antenna unit 12 are arranged linearly. In this way, the antenna unit can be arranged as close as possible to the edge of the display screen 10 to avoid affecting the touch control, light output and related optical performance of the display screen 10 .

As shown in Figures 2-6, when the first antenna unit 11 and the second antenna unit 12 are alternately arranged, the vertical distance between the first antenna unit 11 and the edge of the display screen 10 is the distance from the second antenna unit 12. The vertical distances from the same edge of the display screen 10 are the same.

As shown in Figures 7-8, when the first antenna unit group 15 and the second antenna unit group 16 are alternately arranged, the vertical distance between the first antenna unit 11 in the first antenna unit group 15 and the edge of the display screen 10 The distance is the same as the vertical distance from the second antenna unit 12 in the second antenna unit group 16 to the edge of the display screen 10 .

In other embodiments of the present application, as shown in FIG. 9 , the first antenna unit 11 and the second antenna unit 12 are arranged in a non-linear manner. In this way, the spatial coverage of the beams of the antenna array and the receiving strength of the signal can be further improved, and the degradation of the antenna performance due to hand-holding or other obstructions can be reduced.

As shown in Figure 9, when the first antenna unit 11 and the second antenna unit 12 are alternately arranged, the vertical distance between the center of the first antenna unit 11 and the edge of the display screen 10 is displayed with the center distance of the second antenna unit 12 The vertical distances of the edges of the screen 10 are different.

Four first antenna units 11 are disposed on the second edge region B of the display screen 10 to form another first antenna unit group 15 . The orthographic projection area of the radiating part 17 of the first antenna unit 11 in the first antenna unit group 15 arranged on the first edge area A of the display screen 10 on the substrate of the display screen 10 is larger than that arranged on the display screen 10 The area of the orthographic projection of the radiation portion 17 of the first antenna unit 11 in the first antenna unit group 15 of the second edge area B on the substrate of the display screen 10 is therefore set in the area of the first edge area A of the display screen 10 The frequency band of the first antenna unit group 15 is lower than the frequency band of the first antenna unit group 15 disposed on the second edge area B of the display screen 10 .

Four second antenna units 12 are disposed on the second edge area B of the display screen 10 to form a second antenna unit group 16 . Four second antenna units 12 are disposed on the third edge region C of the display screen 10 to form another second antenna unit group 16 . The orthographic projection area of the radiation part 17 of the second antenna unit 12 in the second antenna unit group 16 of the second edge area B of the display screen 10 on the substrate of the display screen 10 is smaller than that of the second antenna unit 12 arranged on the display screen 10 The area of the orthographic projection of the radiation portion 17 of the second antenna unit 12 in the second antenna unit group 16 of the third edge area C on the substrate of the display screen 10 is therefore set in the second edge area B of the display screen 10 The frequency band of the second antenna unit group 16, high In the frequency band of the second antenna unit group 16 disposed on the third edge area C of the display screen 10 .
